in anwser to your re, Herwig:

MOT's are allways lethal, since they give aprox 2300 V-at-500mA that makes them
rather deadly.

and for the leads comming out, you could check my page and click to the MOT
pictures.
the 2 other leads are from 3 volts used for the microwave fan.
that you've got 3 is because the 4th is connected to the core.
disconnect it from the core and use it with your other secondary wire.
TATAAAA.
